Thanks for the replies, so it appears I got my calc's wrong, based them on the wrong voltage and did not know about the 80% discharge idea. I will plug the watt meter in over the next day or so for some readings. The blocks are turnigy nano-tech and were expensive which is why I wanted to...

Based on similar calculations a year or so ago I had purchased 6s+4s worth of 6aH rc-Lipo batteries, presuming this should have equalled to 42v x 6a to give me 252watts of total power. My journey used aprox 120w each way 240w total, so this battery should be ok, right? Nooo.... Today I tried my...

+1 for the Marathon Plus tyre. Over 13'000 miles puncture free so far on mine.

Incidentally, what controller are you using the 63v battery on?

That one above was vertical too... Now I know the barrel which the moving magnets and brake cable goes through is seperate to the electronics I am considering pouring some acf50 or thick oil in and hopefully coat the magnets and the bit it slides along to protect in the future.

I think it was from the rust as the inside magnet was seized. This is about my 3rd sensor to fail over 3 years so was interested to find out why and am now thinking of ideas to prevent the rusting inside.

I've always wondered how these brake cutoff sensors work so having another one fail I decided to take it apart. The 2 brown rusty blocks are magnets, the end one is fixed and the inside one is supposed to be loose which I believe sticks to the cable (even the stainless cables are magnetic...

Just had an idea from another thread, Could I plug this 8.4v 1a cree battery mains charger measuring 8.35v directly onto that 2s lipo battery discharge plug to charge it if I keep an eye on the balance of each cell? or will the battery blow the plug up?

No because the charger will reduce the amps as it gets nearer the end. You can either rig up a watt meter between the battery and the charger or get a plug in power monitor gadget which should include watts used, then knock off about 20w to allow for the charger power. I used this one before...

I think that should fully charge your batteries in 5 hours. You've given me an idea to get the 25.2v 6s version of your charger to bulk parallel charge my 6s packs but first do let us know how you get on with it. I also like the look of cwah's charging unit too.

Yes, I was at about 13'550 ish and the odo reset to 00000 It's took me 3 years exactly last week.

Back up and limping along with no LCD and throttle only. My old battery does not like the throttle (volt sink) but I'm going to eeek out every last drop of energy out of it. I've shorted the red/blue controller wires together (thanks d8veh for info in the past) and fitted the old throttle back...

Super. Just what I need too.

Your not kidding, This year I've been trying this - stuffing a small hot water bottle up my jacket. Seems to work ok. I'm also trying some wheatybags , warmed and stuffed up my jacket cuffs if they are small enought when they come, to hopefully warm my wrist/hands

You got me thinking about when the volts on the old battery get low 32v'ish they tend to bounce a bit and the motor judders which tells me to quickly turn the PAS level down or it cut's out. Also have just looked at the anderson plugs on the batteries/controller and they are black and oxidised...

After collecting 36 miles on my odo over the last couple of days since this. ****** IT GETS WORSE ******* Today the LCD will not switch on at all, it's dead but has battery volts to it !! Had to drive for a change. Might start a new thread on the LCD after I've done...

Bike for sale, good as new 00000 genuine miles on the clock. New signature below

My old battery cutout yesterday as it has been doing lately(it's on it's way out) so swapped to my spare as usual. When I switched on my ODO had reset to 00000 AAARRRGGGHHH !!!! Earlier this week it had just passed 13'500 miles. I was collecting cycle miles like points and...

Thanks, both answers good to know, I will connect together and try out over the weekend. Also it's good to know about sw's switch as I bought one and was going to bin it when yours give up, so may be able to use it after all. I am guessing I should get with 2 lights@1a about - 3 hrs and 3...

If you're not in any rush to charge quick then this 50w charger is cheap, has no fan and is silent and I think would take 5hours to charge your 3 packs in parallel on a parallel board...
